TAI/BOT C. DEXTER, OF PEARL RIVER, NEW YORK, ASSIGNOR TO THE DEXTER FOLDER COMPANY, OF NEW YORK, N. Y.

PAPER-REGISTERING INSTRUMENT.

:EPECIFXCATION forming part of Letters Patent No. 669,061, dated February 26, 1901.

Application filed December 6, 1898. Serial No. 698,494. (No model.)

' citizen of the United States, and a resident of Pearl River, in the county of Rockland, in the State of New York, have invented new and useful Improvements in Paper-Registering Instruments, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of automatic paper-registering instruments shown in my Letters Patent No. 554,913, dated February 13, 1896, in which the registering of the paper is effected by means of verticallymovable pins dragging upon the paper and dropping into slits in the paper for that purpose, said pins having attached to them horizontal disks by which they ride upon the paper when the pins are dropped into the slits, as aforesaid. The succeeding lateral movement of the pins causes the paper to be shifted to its registering position.

In practice I have found that in operating the aforesaid registering instruments upon thin or light-grade paper the lateral movement of the registering-pins while entering into the slits causes said pin to press against the front edge of the slitted portion of the paper sufficiently to crimp the paper thereat before the disk on the pin was brought to bear on the paper to obtain its frictional hold thereon.

The object of my present invention is to obviate the aforesaid defect and to render the registering instrument more efcient in general; and to that end the invention consists in the improved construction and combination of parts hereinafter described, and summed up in the claims.

In the accompanying drawings, Figure 1 is a Vertical longitudinal section showing my improved point-feed registering instrument applied to a paper-folding machine, the side registering device being omitted to better illustrate my invention. Fig. 2 is a top plan view of the folding-machine to which my invention is applied. Fig. 3 is an enlarged side View of the longitudinal registering mechanisms. Fig. 4 is an enlarged plan view of the carrier of the longitudinal registering instrument. Figs. 5 and 6 are vertical transverse sections on lines X X and Y Y, respectively, in Fig. 1. Fig. 7 is an enlarged side View of the machine, showing the mechanism for operating the gripper employed for registering the paper laterally. Fig. 8 is a side View showing the mechanism for operating the longitudinal registering instruments. Fig. 9 is a Vertical transverse section on line Z Z in Fig. Eig. 10 is a detached plan view of the adjustable attachment of the gage to its actuating-bar. Fig. 11 is an enlarged detail view of the attachment of the pitman to the rock-arm which transmits motion to the longitudinal registering instrument, and Fig. 12 is a plan View of a sheet of paper having circular perforations by which to register said sheet.

Similar letters of reference indicate corresponding parts.

A represents the supporting-frame of a paperfolding machine, which frame may be of any suitable shape to accommodate the number of folding-rollers and actuating mechanisms required to make the desired number of folds in the paper.

B B designate the first pair of folding-rollers. a d are the usual tapes which convey the paper into the folding-machine.

C denotes the feed-roller; D, the drop-rollers; E, the usual blade which tucks the paper into the bite of the folding-rollers, and b the front stop or gage which arrests the movement of the paper carried into the machine by the conveying-tapes ct a preparatory to the introduction of the paper into the bite of the folding-rollers.

o. ct/ denote the usual bars which support the portion of the paper lying between the folding-rollers B and gage b.

F represents the registering instrument by which the sheet is registered late rally afte r said sheet has been arrested in its forward movement by contact with the gage b, and Gr G represent the registering instruments by which the sheet is registered longitudinally after it has been registered laterally. There are two of said instruments G G, disposed equidistant from opposite sides of the longitudinal central line of the machine and on a line at right angles to said central line. My inven- IOO llongitudinally and guided on said arm.

tion pertains more particularly to these longitudinal registering instruments G G, which I will now proceed to describe, with their actuating mechanisms and auxiliary devices elnployed in connection therewith.

Transversely over the papersupporting bars ct is a-rigid bar c, mounted on standards A', fastened to the top of the frame A. To the under side of the bar c are attached two guides c', disposed parallel with the papersupporting bars a. In these guides slide bars c2, to which is adjustably secured the gage b. The adjustable attachment of said gage is more clearly shown in Fig. lO of the drawings and consists of a longitudinal slot .o3 on the bar c2 and the attaching-screw c4,

passingthrough said slot and into a screwthreaded socket in the gage. The adjustability of said gage is necessary to accommodate it to different-sized sheets of paper fed to the machine. Across the end of the frame A, adjacent to the gage b, extendsa horizontal rock-shaft b', journaled in suitable bearings attached to the frame. To this rockshaft are fastened arms b2, the free ends of which are bifurcated or slotted longitudinally, by which they straddle wrist-pins b3 on the bars c2, as clearly shown in Fig. 8 of the d rawings. The shaft b has an intermittent rocking motion, which causes the gage b to be carried back and forth at regular intervals of time. Said motion is derived from a rotary cam F on a shaft F2, upon which cam bears a roller d, pivoted to the free end of an arm f3, attached to the shaft b. Upon the crossbar c ride two brackets e, which are fitted to it by dovetail grooves c in the under sides of the brackets and embracing a correspondingly-shaped horizontal web e2 on the bar c. Each of the brackets e is formed with a post c3, to which is adjustably secured a horizontal arm f by means of the attaching-bolt f', passing through a vertical slot in the post and provided with a nut'f2, by which the arm is clamped in position. Upon the arm f rides one of the registering instruments G,consisting of a shoe or carrier g, which is movable Said movement is retarded by means of frictionplates g', adjustably secured to the carrier g by means of screws g2,\vhich plates pinch the arm f, for the purpose hereinafter explained. To the carrier g is pivoted a T-shaped lever h, the vertical limb of which is connected by a pitman h to an arm h2, fastened to a rockshaft h3, which is actuated by a lever h4, fastened to the end of said shaft and having pivoted to its free end a roller h5, by which it bears on a rotary cam h6, shaped to impart an intermittent oscillatory motion to said lever. The said pitman is longitudinally adjustable in its connection with the rock-arm h2, as shown in Fig. l1, to allow the registeringinstrument G to be adjusted to carry the paper to its requisite registering position. From one end of the horizontal limb of the lever 7i is suspended the paper-registering pin P, which is specially designed to be used for registering paper which is provided with circular perforations O, as shown in Fig. 12 of the drawings, and for that purpose the lower end of the pin P is formed with a conical point P/ to guide said pin into the perforation O during the descent of the pin, which at that time has its pendent portion yielding laterally. Imm ediatelyabovethe point P the pin is formed cylindrical, as shown at P2, to occupy the perforation O when the pin is inserted and bearing upon the sheet by the disk t', of rubber or other suitable material, attached to the pin immediately above the cylindrical portion P2. The bevel of the point P and its ability of yielding laterally in entering into the perforation O effectually guard against crimping or tearing the paper,and the straight cylindrical portion P2, subsequently occupying the perforation while the disk t' bears upon the top of the paper, affords a safe and effective hold for the registering-pin for moving the paper to its registering position. A spiral spring P3, interposed between the horizontal limb of the lever 7i and a shoulder P4 on the pin P, serves to exert a yielding downward pressure on the pin.

To effect the movement of the paper, I provide the carrier g with movable jawsjj, disposed at opposite sides of the registering-pin P and shaped to `grip said pin after it has dropped into the perforation O, as aforesaid. Said jaws project from plates j j, sliding` longitudinally on the carrier g and between guides t t", attached to said carrier. I preferably operate the jawsjj by the same mechanism which moves the carrier and lifts the registering-pin, and for that purpose I pivot to the carrier g a three-armed lever Z and connect two of its arms to the plates j j by rods l l. The third arm of said lever I connect to the forwardly-extending limb of the lever h by a link or rod Z3.

In order to limit the upward movement of the registering-pin, a set-screw t is inserted into a screw-threaded eye in an ear t, which projects from the side of the carrier q back of the vertical limb of. the lever 7L, which limb strikes the set-screw, and thereby arrests the movement of lthe lever t when it has lifted the registeringpin P sufficiently from the paper.

The operation of the described registering instruments is as follows: The paper having been carried into the machine by the tapes a, CL and arrested in its movement by contact with the gage b, which at that time is in its rearmost position or closest position to the folding-rollers, then the lateral registering instrument F, hereinafter described, draws the paper to its side register, and thereby brings the perforations O O into position to allow the registering-pins P P to enter in to said perforations, and then the gage b recedes from its aforesaid sheet-arresting position. In the meantime the registering instruments G Gare sustained in their rearmost position and with their registering-pins P P lifted from the paper, as represented in Fig. 1 of the drawings. In pushing the instrument G into the aforesaid position the pitman 7?/ first tilts the lever ZL so as to lift the registering-pin Pbefore moving the carrier ]which is retarded in its movement by the friction-plates g pinching the arm f, so as to partially bind the carrier on the said arm, as hereinbefore described. In tilting the lever h, as aforesaid, the vertical limb thereof comes in contact with the setscrew T, which arrests the further tilting of the lever and causes the pitman h' to push the carrier toits aforesaid rearmost position. The pitman is then moved in the opposite direction by the rock-arm h2, and the lever ZL is thereby actuated to allow the registering-pin P to drop and to be guided into the perforation O in the paper by the conical point P' on the laterally-yielding lower end of the pin. In this manner the pin is made to ride on the paper by the disk fi., while the cylindrical portion P2 of the pin occupies the aforesaid perforation, and thus the paper is relieved from liability of being crimped or torn by the introduction of the registering-pin and said pin obtains a safe and perfect hold on the paper. During the aforesaid introduction of the registering-pin the carrier gis held stationary by its frictional hold upon the arm f, and this causes the lever Zt to actuate the lever Z, so as to force the jawsjj to grip the registeringpin P, and this engagement restrains the levers Z and h from further tilting movement and causes the pitman hl to draw the carrier forward or toward the gage h. The pin P, being in the meantime engaged with the paper and firmly gripped by the jaws jj, causes the paper to be shifted to its registering position. The subsequent reverse or rearward movement ot' the pitman h tilts the levers h and Z, so as to first move the jaws out of engagement with the registering-pin P and then lift said pin from the paper. Said successive action is permitted by lost motion or play between the head of the pin and top of the lever, as represented at p in Figs. 3 and 4 of the drawings. The movement of the pitman h is so timed as to cause the registering-pin to be lifted in time to allow the blade E to tuck the paper into the bite of the folding-rollers B B. The perforations O are made in the paper by means of dies set in the form carried on the press-bed, and inasmuch as said dies have to be set various distances apart, according to the sizes of the sheets to be printed, it is necessary to provide means for very accurately adjusting the registering instruments G Glaterally to conform their positions to the locations of the perforations. For the aforesaid adjustment l employ two separate adjustingscrews s s, one for each of said registeringinstru ments. Said screws are in line with each other and extend horizontally to opposite sides of the frame A, where they are journaled in suitable boxes s s', mounted on the frame. The inner end of each screw passes It is sometimes found necessary to shift both registering-pins laterallyiu the same direction, and in order to permit this to bo effected expeditiously` and conveniently I provide a suitable coupling, which may be of the form shown in Fig. 2 of the drawings, consisting` of two collars u fu, rigidly united by bars z fu. Each of said collars loosely embraces the inner end of the adjacent screw s and is provided with a set-screw U, by which to fasten the collar to the screw when desired to adjust the two registering instruments simultaneously.

The lateral registering instrument F may be of anysuitable and well-known form. The annexed drawings show it to consist of a gripper similar to that shown in my Letters Patent No. 599,319, dated February 22, 1898, and consists, essentially, of a shoe k, receiving through it the marginal portion of the paper and provided in its top with an aperture through which plays the paper-gripping finger fn, which is actuated by a rocking plate n', playing in a tumbler o, attached to the shaftofthegripper-finger. Saidrocking plate is attached to a shaft which receives rocking motion from a rotary cam m, imparting oscillatory motion to a lever m, connected by a rod m2 to an arm w, attached to the aforesaid shaft. mittent recqirocating bar 7a', by which said shoe receives its requisite motion for drawing the paper laterally to register. The bar Zt is actuated by a rotary cam Qc, oscillating a lever which is connected .to the said bar, as shown in Fig, 2 of the drawings.
